The more vents, the better.

It's true, we're starting to see an industry trend that's leading
away from helmet ventilation in favor of aerodynamics. However, the
question begs to be asked, 'what are you willing to give up for marginal
gains?' And while we're a fan of free speed and innovation, in our
books, ventilation is king. Not surprisingly, Louis Garneau agrees, and its new Diamond II Helmet takes this idea and rides away with it.

In fact, we detect a slight hint of one-upsmanship. While the
industry overkill of ventilation has for years been dominated by the
Whisper Plus' 39 vents, the Diamond II features 40 and weighs in around a
svelte 285 grams. And on top of this, the Diamond II met all North
American certifications right out of the gate. So, you can be assured
that increasing safety is still the paramount feature of this helmet.
So, how did Garneau do it? Its patented Super MSB (Monocoque Structural
Base) and EXI technologies, of course. Basically, these two designs work
in unison to eliminate the commonality of rib construction in helmets.
As Garneau puts it, the prior means of manufacturing adds weight and
minimizes the amount of potential ventilation, all the while without
increasing safety. And while all of that sounds pointless and archaic,
the solution was complicated from engineering standpoint.

The path to the Diamond II took a few steps. The Super MSB structure
is basically a supportive base that's akin to an exoskeleton. It has a
polycarbonate, monocoque construction, meaning that it's formed in one
piece. This reinforces the perimeter of the helmet, while supporting the
EXI-insert with confidence -- and this is where the rib-replacement
comes into play. Together, the two systems position two polycarbonate
bars within the helmet structure, with an additional nine carbon fiber
bridge inserts. The system provides targeted structural support to the
helmet in the case of collision. For further reinforcement, the entire
structure is created with In-Mold construction. This means that the
helmet's shell and foam liner are molded together at the same time.

With Garneau's new structural design, it was able to increase the
ventilation without degrading strength. But Garneau wasn't finished with
the Diamond II's comfort. The helmet features what Garneau calls its
Evacuation Channels. These ports in the helmet provide an increased
airflow over the head, while creating a dispersion of internal moisture.
To secure the helmet, Garneau incorporated its Spiderlock PRO II
stabilizing system that permits one-handed adjustments to the helmet's
retention. It also has a polymer neck support and an anti-slip
turn-wheel for precise and secure adjustment. At the chinstrap, the
Diamond II comes equipped with cam-locking device that simplifies the
process of dialing-in the helmet's fit. And lastly, Garneau also
included X-static XT2 padding internally for its antimicrobial,
comforting support.

And as if a helmet wasn't enough protection, the Diamond II features a
reflective decals and a Spiderlock Vision light that fits over the
stabilizing wheel at the rear of the helmet. So, your visibility is
effortlessly increased to passing motorists in low-light conditions.

The Louis Garneau Diamond II Helmet is available in the sizes Small, Medium, and Large and in the colors Black, Red, and White Customizable.
